ch.aplu.ev3.HTEopdShortSensor

public class HTEopdShortSensor
extends Sensor

Class that represents an Electro-Optical Proximity Detector (HiTechnic EDPD). The sensor measures distance uniformly colored objects in range of about 15 cm. It is much less effected by ambient light than a standard color or light sensor.

Constructor Detail

HTEopdShortSensor

public HTEopdShortSensor(SensorPort port)

Creates a sensor instance connected to the given port in short distance mode. The short distance mode is used to detect white objects at close distance.

Parameters:

port - the port where the sensor is plugged-in

HTEopdShortSensor

public HTEopdShortSensor()

Creates a sensor instance connected to port S1 in short distance mode. The short distance mode is used to detect white objects at close distance.

Method Detail

getLejosSensor

public lejos.hardware.sensor.HiTechnicEOPD getLejosSensor()

Returns the reference of the the underlying lejos.hardware.sensor.HiTechnicEOPD.

Returns:

the reference of the lejos.hardware.sensor.EV3ColorSensor

getDistance

public int getDistance()

Polls the sensor.

Returns:

the current value the sensor reported in arbitrary units from 0..999 (999 if the sensor does not detect a target)
